TYPE-WRITER ATTACHMENT.

I SPECIFICATION forming part of Letters Patent No. 590,404, datedSeptember 21, 1897'.

Application filed April 7, 1896. Serial No. 586,494. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM J. RENO, of the city of Minneapolis, countyof Hennepin, State of Minnesota,have invented certain new and usefulImprovements in Type-WVriter Attachments, of which the following is aspecification.

My invention relates to attachments for type -writers, caligraphs, andsimilar machines; and the object I have in view is to provide a devicewhich will enable the opera tor of the machine to print invoices of allkinds and tabular statements comprising several columns of figureswithout the necessity of raising the type-writer carriage during theprogress of work.

My invention consists generally in providing an auxiliary scalesupported upon the type-writer independently of the main scale and aseries of pointers also independently supported, said auxiliary scaleand pointers being slidably arranged, the formerbeing provided with aseries of characters whereby the proper position in the column of thecharacters that it is desired to print may be ascertained withoutraising the type-writer carriage, all as hereinafter described, andparticularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a view of the front of a type-writer with my invention appliedthereto. Fig. 2 is a plan view of the same. Fig. 3 is a sectional viewshowing the manner of securing the attachment to the type-writer. Fig. 4is a detail view of the centering device. Fig. 5 is a front view showingthe device attached to the type-writer carriage and movable therewith.

In the drawings, 2 represents the frame of a type-writer, 3 thecarriage, 4 the wheel arranged to roll upon the frame of the machinenear the main scale and supporting the forward end of the carriage, 5the pointer, and 6 the main scale, all these parts being of the ordinaryconstruct-ion and such as are shown in many type-writers.

To the forward side of the frame 2 I secure my attachm ent, whichcomprises the brackets 7, secured to the frame by the set-screw 8, asshown in Fig. 3, and connected by the inner rod 9 and the outer flexiblerod 10. Upon the rod 9 Iprovide a series of movable pointers 11 and anauxiliary scale 12, also ar-' ranged to move back and forth upon the rod9 and provided with a series of pointers 13, extending partially overthe main scale 6, there being four spaces on the scale between every twopoints 13. The auxiliary scale 12 is also provided upon its surface witha series of naughts and periods and is slotted on its forward edge toreceive a block 14, slidably arranged upon the rods 9 and 10 and adaptedto hold the same parallel. This block is preferably provided with a knob14. By means of this block the auxiliary scale 12 may be moved back andforth over the main scale,

and as the rod 10 is arranged to bear uponthe pointers 11 and theauxiliary scale 12 to prevent the same from being moved by the jar ofthe machine the block also serves to hold the rod 10 in position andprevent it from sagging and getting out of engagement with the surfaceof the pointers 11 and the auxiliary scale 12. Each of the smallpointers is preferably provided with a cup-shaped recess which isadapted to receive the point of a pencil by which the pointer may bemoved.

The rod 10 constitutes a rest for all of the pointers and the auxiliaryscale when they are turned back from the main scale so as to leave thelatter entirely unobstructed,- and this rod also holds the pointers andauxiliary scale away from the keys and type-bars.

In invoicing the auxiliary scale maybe used to carry out the totals ofextensions by beginning at the right-hand end of the scale and, guidedby one of the series of naughts or characters on the surface thereof,printing the extensions in a column for the purpose, and then, guided bya series of naughts or characters to the left of the first series,printing the total of the extensions in a column to the right thereof.

In Fig. 5 I have shown the. device attached to a more modern style oftype-writer in which the main scale is arranged upon and movable withthe type-writer carriage, and the pointer, which in the older style oftype-writers'is attached to the carriage, is in thenew machines fixed tothe frame beneath the main scale. When used with this style oftype-writer, the auxiliary .scale, as shown in the drawings, issupported independently of the main scale by the brackets 7, arrangedupon the carriage.

The operation of the device is as follows: Suppose it is desired toprint a column of words or numerals under the space marked 10 on themain scale, another column of words under the space 25, and athird underthe space 60. One of the pointers 11 is set at each one of these pointsand the carriage moved so that the pointer 5 will be opposite one of thepoints 11. The operator having printed the desired figure or characterat the three different points indicated by the pointers 11, the carriagemay be moved back and the operation repeated without the necessity ofraising the carriage to determine the exact position of the figures orcharacters previously printed, as their position will be indicated bythe pointers 11. Any desired number of pointers may be provided, so thatthe operator may print as many columns as the length of the main scalewill permit. The auxiliary scale is of a special value when it isdesired to make'tabular statements comprising figures from very low tovery high denominations. WVhen it is desired to print a column of thesecharacters, the auxiliary scale is moved to the desired point on the rod9,and if 1,000.00 is to bewritten the pointer on the carriage is moveddirectly over the first cipher or figure to the right of the secondperiod on the left-hand end of the auxiliary scale. If the next amountis 1,000,000.00, it will be brought over the first cipher to the rightof the third period, and so on. Any number may thus be properly locatedwithout raising the carriage, so as to bring them all in the properrelation to one another in the column.

It will be noticed that on the auxiliary scale there is a pointer aboveand opposite each period and extending partially over the main scale, sothat the proper position for the carriage can be easily determined.

The operation of the device when arranged upon the machine in the mannershown in Fig. 5 is substantially the same as that described above.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination, with the type-writer frame and itscarriage, of the main scale, a

movable auxiliary scale supported independently of said main scale, saidauxiliary scale being provided upon its surface with a series of figuresor characters and having a series of points extending across the face ofsaid main scale, for the purpose set forth.

2. In a type-writer, the combination with the main scale, of the movableauxiliary scale, the rod Whereon said auxiliary scale is movable, meansfor preventing said auxiliary scale from being moved by the jar of themachine, and a block adapted to engage said brackets, pointers slidablyarranged on said bar, the auxiliary scale, a. second rod or wireconnecting said brackets and arranged to bear upon the surface of saidpointers and on the auxiliary scale, for the purpose set forth.

'5. A type-writer attachment comprising a rod or bar, adapted to besupported upon the type-writer, an auxiliary scale slidably arrangedupon said bar, said auxiliary scale being provided on its surface with aseries of naughts and periods, and being also provided on its edge witha series of points or proections opposite the periods upon the surfaceofsaid auxiliary scale, for the purpose set forth.

6. The combination with the type-writer frame and its carriage, of themain scale, the series of pointers slidably arranged adjacent to saidscale, said pointers being provided in their surface with a depression,for the purpose set forth.

7. An invoicing attachment for typewriters, comprising an auxiliaryscale, supported independently of the main scale and provided upon itssurface with a series of naughts or-characters arranged ingroupsrepresenting different denominations of figures, to permit the device tobe set opposite the pointer to tabulate a column of figures, and tocarry out the extension of the same into another column without movingthe auxiliary scale from its original position, substantially asdescribed.

8. The combination, with the type-writer frame and its carriage, oneprovided with the fixed pointer and the other with the main scale, ofthe pointers slidable or movable with respect to said scale, the movableauxiliary scale, and means whereby said pointers and said auxiliaryscale are together supported independently of said main scale,substantially as described.

In testimony whereof I have hereunto set my hand this 17th day of March,A. D. 1896.

WILLIAM J RENO.
